Title: Nucleophilic bodies bonded to siloxane and use thereof for separations from sample matrices
Inventor: BETZ WILLIAM R
IPC: B01J20/285
Filed: 1995-02-02
Abstract: A structure comprising bodies having a functional surface property bonded to a substrate via a siloxane polymer adhesive. The structure may comprise a novel composition comprising a siloxane polymer having carbon bodies bonded thereto by direct carbon to silicon bonds. This composition may be used to bond carbon parti-cles through a medium comprising the siloxane polymer to a vitreous, metal, plastic or other nu-cleophilic substrate. Alternatively, the bodies may comprise alumina, silicon zeolite, organic poly-mers or other nucleophilic compositions, which are bonded directly to silicon atoms of the siloxane polymer. To bond carbon or other nucleophilic bodies to the substrate, the substrate is contacted with a mixture of the bodies and a hydrosiloxane polymer. The mixture is heated to cause the poly-mer to be bonded to the nucleophilic bodies, typ-ically by C-Si, C-O-Si, Si-O-Si or Si-O-Al bonds, and to the substrate by reaction with the surface silanol or other nucleophilic groups. Chromato-graphic methods using a column comprising the novel composition are also disclosed.

Filed: 1996-08-08
Abstract: L'invention concerne une chaîne de traction destinée à être montée sur la bande de roulement d'une roue de véhicule, et plus spécifiquement de la roue d'un véhicule lourd tel qu'une débusqueuse. Cette chaîne comprend une pluralité d'anneaux ronds répartis de façon régulière et de telle sorte que chaque anneau soit disposé à une même distance de tous les autres anneaux qui lui sont les plus proches. Cette chaîne comprend aussi une pluralité de maillons montés de façon libre sur les anneaux pour relier chacun de ceux-ci à ceux qui lui sont les plus proches. Chaque maillon est constitué d'une pièce de métal de section rectangulaire sensiblement constante ayant une largeur très supérieure à son épaisseur. Cette pièce forme une boucle aplatie dans laquelle sont librement montés les anneaux. Cette boucle a des faces supérieure et inférieure qui sont planes et s'étendent dans des plans sensiblement parallèles à ceux dans lesquels s'étendent les anneaux adjacents. Cette boucle a aussi des extrémités opposées qui ont la même largeur que les faces supérieure et inférieure et ont chacun une surface interne arrondie selon un rayon de courbure identique ou légèrement inférieur au rayon des anneaux. Grâce à la forme de ses maillons plats qui peuvent être pourvus de crampons si cela est nécessaire, cette chaîne de traction est non seulement très efficacemais très résistante. En fait, sa durée d'utilisation est presque le double de celle des chaînes existantes.

Title: Methods for modulating t cell responses by manipulating a common cytokine receptor gamma chain
Inventor: BOUSSIOTIS VASSILIKI A
IPC: A61K38/20
Filed: 1995-06-30
Abstract: When stimulated through the T cell receptor (TCR)/CD3 complex without requisite costimulation through the CD28/B7 interaction, T cells enter a state of antigen specific unresponsiveness or anergy. This invention is based, at least in part, on the discovery that signaling through a common cytokine receptor .gamma. chain (e.g., interleukin-2 receptor, interleukin-4 receptor, interleukin-7 receptor) prevents the induction of T cell anergy. This .gamma.  chain has been found to be associated with a JAK kinase having a molecular weight of about 116 kD (as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis) and signaling through the .gamma. chain induces phosphorylation of the JAK kinase. Accordingly, methods for stimulating or inhibiting proliferation by a T cell which expresses a cytokine receptor .gamma. chain are disclosed.
